Yeah, my husband has a penicillin allergy too, and we always have to be vigilant about making sure he doesn't get prescribed that by accident. Having a food allergy must be much worse, since you have to wonder what's in everything you're eating. So I do sympathize. I just think that expecting parents of non allergic children to divine if a non peanut cookie has been made in a bakery that also uses peanuts in other stuff, is delusional.

I guess it would be different if I invited a kid I knew had allergies to my house or something. But to expect every parent to care and conform at a large school event where everyone has been asked to bring a treat including themselves - that's just rude.
